until you see the detector flashing the compass LEDs

clockwise, one after another.

• Drive your vehicle in two circles. The size of the circles

and the direction that you drive does not matter. The

circles do not need to be perfect circles but must be

completed in the same direction. Each circle should

take a minimum of 20 seconds but no more than 1

minute to complete.

• Press the CALIBRATE button (CITY button).The

detector will end the compass calibration in two beeps

and with the 4 compass LEDs flashing twice altogether.

The compass screen will indicate which direction your

vehicle is pointing. Calibration is now complete.

While the detector is calibrating, the front screen will

remain completely blacked out.

• When to Calibrate: The compass must be calibrated:

- When the detector is used for the first time in a

vehicle, and

- When the detector is mounted in a new location.

• Compass Display: The compass periscope displays 8

cardinal points.
